day3 vs. Mailchimp
A Mailchimp alternative that charges for sends, not your list size.
Mailchimp is a broad marketing platform, and its bill climbs as your contact count grows — even in a month you send nothing.
| day3 | Mailchimp | |
|---|---|---|
| Pricing model | By emails sent each month | By number of contacts/audience size |
| Subscriber limits | Unlimited on every plan | Tiered — more contacts cost more |
| Product scope | Product updates & newsletters, on purpose narrow | Full marketing suite (automations, ads, CRM, sites) |
| Best for | Founders & small SaaS sending updates | Marketing teams running campaigns at scale |
| Starting price | $1/mo for 1,000 emails | Free tier, then priced by contacts |
Comparison reflects each product's pricing model and scope, not specific prices — those change, so always check the latest on Mailchimp's own site.
The core difference
day3 decouples list size from price. Keep any number of subscribers and pay only for the emails you send — so a big list you email occasionally costs far less.
Why teams move to day3
No contact tax
200 contacts or 200,000 — same price. The meter is sends, nothing else.
Nothing to configure
No journeys or automation to wire up first. Write the update, pick a list, send — saved segments are there if you want them, not a prerequisite.
Deliverability included
Authenticated domains, one-click unsubscribe, and auto-suppression come standard, not as an upsell.
When Mailchimp is the better choice
Stay with Mailchimp if you need automation flows, landing pages, ads, or a CRM in one place. day3 does none of that — it just emails your users about product changes.
Questions
- Is day3 cheaper than Mailchimp?
- Usually, for a growing list — day3 never charges by contact count. Your bill tracks emails sent, not audience size.
- Can I migrate my Mailchimp list to day3?
- Yes — by CSV or API. Export your subscribers and import them into a day3 audience, or script it against the API in batches of 1,000, bringing your custom fields and opt-outs with you. Either way the import dedupes and drops anyone who unsubscribed or bounced.
- What does day3 not do that Mailchimp does?
- By design: no automation flows, A/B testing, drag-and-drop template builders, landing pages, or ads. Just reliable product emails — with saved segments and subscription topics where they earn their keep.
